Charleston’s humidity and salt air take a toll on HVAC systems. Ducts collect mold spores, dust mites, and allergens faster here than in drier climates, and when a system hasn’t been serviced in years, that buildup starts circulating through the home. Finding air duct cleaning companies offering inspection and cleaning services in Charleston takes more than a quick Google search; quality, credentials, and scope of work vary quite a bit from one provider to the next.
How to Choose an Air Duct Cleaning Company in Charleston
A few things separate a solid provider from one that just shows up, runs a vacuum near a register, and leaves. NADCA membership is the clearest credential to look for; it means the company follows the National Air Duct Cleaners Association’s cleaning standards, which require source removal rather than surface-level passes. BBB accreditation and Google review volume are useful signals, though neither replaces verifiable industry certification.
For Charleston specifically, ask whether the company has dealt with mold-related ductwork issues before. The region’s climate pushes moisture into HVAC systems year-round; a technician who skips the mold check during inspection is leaving out a meaningful piece of the job. Before-and-after documentation – photos or video – is another thing worth raising upfront. Reputable companies offer it without being asked.
1. R&E Home Solutions
R&E Home Solutions is a family-owned Charleston company whose work spans air duct cleaning, dryer vent cleaning, mold inspection and remediation, and water damage restoration. They’ve held NADCA membership since April 2020, employ ASCS-certified staff, carry a BBB A+ rating with zero complaints on file, and have pulled in over 800 five-star Google reviews, the strongest review profile among the companies on this list. Depending on system conditions, their technicians use either negative air pressure equipment or a rotobrush machine, and every job comes with before-and-after photos sent directly to the client. Here’s the thing: they use only organic products across all services, which matters more than people expect in households with young children, pets, or chemical sensitivities.
Beyond duct cleaning, R&E handles UV light installation for ongoing air disinfection, attic cleaning, crawl space solutions, chimney sweeping, and hood vent cleaning. Residential duct cleaning typically runs $300 to $500; commercial systems range from $1,000 to $5,000. Same-day and emergency service are available. Their team is trained to catch the mold growth and salt corrosion that Charleston’s climate accelerates, a locally relevant detail that generic HVAC cleaners tend to miss entirely.
Features:
- NADCA membership with ASCS-certified personnel; BBB A+ accredited
- Negative air pressure and rotobrush equipment; before-and-after photo documentation
- Organic products used on every project
- Mold inspection, remediation, and UV light installation available
- Same-day service; residential pricing $300 to $500
2. CoastalAir Plus
Coastal Carolina Comfort is a Summerville-based HVAC company serving the Charleston Lowcountry, with daily dispatch to West Ashley, Mt. Pleasant, James Island, and surrounding areas. They’ve been operating for over two decades and employ NATE-certified technicians. Duct cleaning and sanitization sits within a broader service menu that includes AC installation, heat pump service, gas furnace repair, crawl space encapsulation, and air purification. The owner actively oversees operations and checks on job progress, a family-business detail that tends to show up, unprompted, in customer feedback.
Their differentiators lean toward their HVAC roots: NATE certification, 24/7 emergency repair availability, and what they describe as a no-high-pressure-sales approach. For homeowners who want duct cleaning bundled with a broader HVAC evaluation, or who need an emergency repair alongside an inspection, Coastal Carolina Comfort is worth considering. The duct cleaning and sanitization service is positioned as part of their indoor air quality menu rather than a standalone specialty.
Features:
- NATE-certified technicians with 20+ years of local operation
- 24/7 emergency repair service
- Duct cleaning and sanitization paired with full HVAC services
- Crawl space encapsulation and air purification available
- No high-pressure sales model; family-owned operation
3. Ductz
DUCTZ of Charleston is a dedicated air duct and HVAC restoration company located in Ladson, SC, operating as part of the Belfor Franchise Group. They serve Charleston, North Charleston, Folly Beach, Goose Creek, Hanahan, Isle of Palms, James Island, Johns Island, Mount Pleasant, and Summerville. Technicians train to NADCA standards and follow EPA post-cleaning consumer guidelines. The service menu goes well beyond duct cleaning: dryer vent cleaning, COILZ condenser coil cleaning, UV light purification, bathroom exhaust cleaning, air duct sealing, and post-construction HVAC cleaning for newly built or renovated properties.
The franchise model has real practical effects. Standardized training and processes can mean consistency across jobs, but it also means less flexibility than you’d get from an independent local operator. DUCTZ serves both residential and commercial clients. For property managers dealing with post-construction dust or fire and water damage affecting HVAC systems, their restoration-specific services are a differentiator few local companies can match.
Features:
- NADCA-trained technicians; EPA post-cleaning guidelines followed
- Post-construction HVAC cleaning and fire/water damage restoration
- COILZ condenser coil cleaning and air duct sealing
- Residential and commercial service across greater Charleston
- Part of Belfor Franchise Group; independently owned and operated
4. Air Duct Cleaning & Repairs
Air Duct Cleaning & Repairs North Charleston, founded in 2015 and headquartered in North Charleston, SC, focuses heavily on commercial duct cleaning. Their client base includes retail centers, office towers, laundromats, and hotels, property types with larger duct systems and higher compliance stakes. The company holds an A+ BBB rating and a consistent five-star Google rating, and they apply NADCA-certified strategies across their commercial process.
Their six-step commercial cleaning process starts with a robotic camera inspection, then moves through negative air pressure vacuuming, rotary brushing, and sanitization fogging before finishing with airflow testing and a final review. The equipment list – HEPA-filter vacuums, negative air machines, specialized agitation systems, robotic cameras, and sanitizing foggers – is well suited for large commercial systems. Residential vent cleaning is also available, though the company’s depth of experience clearly tilts toward commercial accounts. Pricing is described as transparent with no hidden fees.
Features:
- Six-step commercial cleaning process including robotic camera inspection
- HEPA-filter vacuums, negative air machines, and sanitizing foggers
- NADCA-certified strategies; A+ BBB rating and five-star Google rating

5. Fresh Air Duct Cleaning
Fresh Air Duct Cleaning has worked in Charleston since 1998, starting out as Easy Air Ducts before eventually expanding into central air, AC repair, and mold removal. Honestly, that kind of longevity in a local market says something on its own. They’ve serviced homes in Hollywood, Mount Pleasant, Sullivans Island, Hanahan, Wadmalaw Island, and Charleston AFB across nearly three decades, and they’re bonded, insured, and licensed.
Pricing runs on the accessible end: professional air duct cleaning through Fresh Air falls between $80 and $500 depending on system size, accessibility, and cleaning scope. For homeowners working with tighter budgets, that range is worth knowing. Fresh Air doesn’t put money into traditional advertising; their growth has come through referrals and repeat business. That’s a slow way to build a company, but it tends to reflect something real about customer satisfaction, even without a large review footprint. Services cover both residential and commercial buildings.

- Air duct cleaning, AC repair, mold removal, and attic fan servicing

What Inspection and Cleaning Services Actually Cover
A proper duct cleaning job isn’t just a vacuuming pass near accessible registers. During the inspection phase, a technician typically runs a camera or does a visual check of the ductwork interior, looking for debris accumulation, mold growth, disconnected duct sections, or signs of pests. In Charleston, mold is what technicians find most often; the region’s year-round humidity makes it nearly inevitable in older systems.
The cleaning itself should reach every component: supply ducts, return ducts, registers, grilles, diffusers, the air handler, and the drain pans. Source removal – physically dislodging and extracting debris rather than just pushing it around – is what NADCA standards actually require. Companies using negative air pressure equipment create a contained suction environment so that loosened material exits the system rather than redistributing through your home.
So when comparing quotes, ask what the scope includes. A low-cost offer covering only accessible supply vents isn’t the same service as a full NADCA-standard cleaning; the gap matters for air quality outcomes and for how long the results hold before the next service is needed.
Bottom Line
Air duct cleaning companies offering inspection and cleaning services in Charleston range from dedicated indoor air quality specialists to full-service HVAC operators. The right fit depends on what a property actually needs; a commercial building with heavy system use calls for different expertise than a residential home dealing with post-renovation dust or mold-driven humidity damage. Credentials, particularly NADCA membership and BBB accreditation, are the most reliable filters when you’re comparing providers. But whatever company a homeowner or property manager ends up choosing, asking about the inspection process before the cleaning starts is the single most useful thing you can do to gauge whether the job will genuinely be done right.
